I believe that this is the most visited forum on this site. Killing the alt sections can likely kill this website.
Exactly who cares about BTC anymore...
Bitcoins have become too expensive. Most people aren't into cryptocurrencies because they think it's the future. They're into them because they think they'll make money. The BTC boat has sailed- there is still room for growth, in fact quite a bit- but most people are looking into altcoins to make the money they could have made as early adopters of Bitcoins.
This is exactly what is wrong with people who mine and deal with these crapcoins. Cryptocurrencies are meant to be a revolutionary idea as a currency, not a get rich quick scheme. How are Bitcoins too expensive? You can but $10 worth of Bitcoin if you want. You don't need a whole one. Do you really need millions of worthless shitcoins? And how is it too late to get into Bitcoins? If Bitcoin becomes even semi-mainstream those who buy Bitcoins today will probably become pretty well off.
Because you need profits in order to drive interest. That is not hard to understand. You think people would invest in stocks to not make any money? In a way cryptos needs to be kinda like the stock market in order to keep interest going. Without profits no one would mine, and without the mining you have the possibility of broken chains due to attack when someone gets thier panties in a bundle.
